Incorporation and Processing Instructions
To get the optimum efficiency, a complete dispersion of the material is required. Therefore OPTIGEL-CK XR
should be incorporated applying high shear forces e.g. by using a dissolver or a mill. To facilitate the dispersion,
warm water can be used. OPTIGEL-CK XR is then added slowly to the water (emulsion) under slow agitation.
OPTIGEL-CK XR can also be incorporated as powder added to the grind base.
OPTIGEL-CK XR can also be used as pre-manufactured pre-gel (containing 5 – 10 % OPTIGEL-CK XR). To
avoid post thickening effects, this pre-gel should be allowed to age overnight. Stirring for approx. 15 minutes
under high shear is therefore recommended.
Recommended Levels
Depending on application, 0.5 – 3 % of OPTIGEL-CK XR (based upon total formulation weight) is used.

These levels are suggested as guideline; optimum levels can be determined by laboratory tests.
Special Note
OPTIGEL-CK XR is compatible with most emulsions, pigments or extenders. Higher concentration of
electrolytes should be avoided since otherwise the gel structure can be damaged. By using OPTIGEL-CK XR,
storage stable systems can be produced. Due to the thixotropic behaviour, the application is significantly
improved. OPTIGEL-CK XR is purely inorganic and stable against diluted acids and bases. Gels produced with
OPTIGEL-CK XR also withstand oxidation or microbial degradation. OPTIGEL-CK XR is compatible with anionic
and nonionic surfactants.
The non-irradiated base material is available under the name OPTIGEL-CK, but as a natural product this may
contain variable amounts of micro-organisms.
Storage and Transportation
OPTIGEL-CK XR should be stored dry in unopened, original packaging at temperature between 0°C and 30°C.
